In normal weather the pans consist of a series of shallow pools, sandy alkaline clays, and islands of grass and are the habitat of thousands of flamingos.
It is associated with living in areas with high altitude and high seasonal rainfall, and is caused by exposure of bare feet to alkaline volcanic clay soils. 1 Mineral particles are thought to penetrate the skin, causing an inflammatory reaction leading to lymphedema.
Soil nematodes were studied in two chronosequences of plots from open-cast coal-mining dumps near Cottbus Germanyy, acidic tertiary sandy spoils afforested with pines) and near Sokolov (Czech Republic, alkaline tertiary clays afforested with alder).
Here, in an effort to design a more effective procedure for the in situ consolidation of earthen architectural remains, the alkaline reaction of clay-rich earth used in the construction of the Alhambra (Spain) was studied.
The alkaline conditions also support clay conversion in the basin under a low relative temperature condition as a result of thermal subsidence in the basin between Aptian and Cenomanian, in which some of these samples were deposited.
In this study, copper sorption desorption isotherms were obtained for clay-rich, alkaline San Joaquin soil with significant heavy metal sorption capacity, and eroded, acidic Norfolk sandy loam soil having low capacity to retain copper.
The relationship between strength and heat energy can be used as fundamental for further study on the strength development and the mix design method for the clay FA geopolymer with different specimen dimensions, clay minerals, liquid alkaline activators, pozzolanic materials and clay:FA ratios.
Amorphous plasma electrolytic oxidation (PEO) coating with sealed discharge channels can be formed in alkaline phosphate electrolyte containing montmorillonite clay particles.
An alkaline solution, thermally activated kaolinite clay and a mineral additive (calcium carbonate) were mixed with the aim to elaborate a geopolymer material with physical and mechanical properties comparable to those of classical construction materials.
